I-Macrobrachium rosenbergii isakazeke kabanziizinhlanzi zamanzi ahlanzekilengenani eliphezulu lokudla okunomsoco kanye nesidingo esikhulu semakethe.

Izindlela eziyinhloko zokuzalanisaI-Roche shrimpyilezi ezilandelayo:
1. Ukufuya izinhlanzi emanzini okukodwa: okungukuthi, ukufuya izinhlanzi ze-Roche kuphela emanzini amaningi hhayi kwezinye izilwane zasemanzini. Izinzuzo zalolu hlobo lokulima ukuphathwa okulula kanye nenzuzo ephezulu, kodwa izinkinga izidingo zekhwalithi ephezulu yamanzi, ukuvela kalula kwezifo kanye nokudla izilwane ezidla ezinye izilwane.
2. Ukufuywa kwezinhlanzi ezixubile: kubhekisela ekulinyweni kwezinhlanzi zasemanzini zaseRoche nezinye izilwane zasemanzini njengezinhlanzi, iminenke, ama-clam, njll. endaweni efanayo yamanzi. Inzuzo yale modeli yokufuywa kwezinhlanzi ukusebenzisa isikhala esinezingqimba eziningi zomzimba wamanzi, ukuthuthukisa umkhiqizo wamanzi, ukwandisa imithombo yemali engenayo, nokunciphisa ukuncintisana nokudla phakathi kwezinhlanzi zaseRoche, ngaleyo ndlela kuncishiswe ukuvela kwezifo. Kodwa ububi ukuthi ukuphathwa kuyinkimbinkimbi, futhi kudingeka kunakekelwe ukukhethwa kanye nesilinganiso sezinhlobo zokuzalela ukuze kugwenywe ukuthonyana kanye nokubamba ukudla.

3. Ukufuywa kwezinhlanzi ngokushintshana kwezitshalo: kubhekisela ekutshalweni okushintshana kwe-Procambarus clarkii nezinye izilwane zasemanzini endaweni efanayo yamanzi ngokwesikhathi esithile, njengokulima izimfanzi emasimini elayisi kanye nokufuywa kwezinhlanzi ezindaweni zerayisi. Inzuzo yale modeli yokufuywa kwezinhlanzi ukusebenzisa ngokugcwele izinguquko zesizini ezindaweni zamanzi, ukufeza izinzuzo ezimbili zemikhiqizo yasemanzini kanye nezitshalo, ngenkathi futhi kuthuthukiswa indawo yemvelo yezindawo zamanzi kanye nokunciphisa ukuvela kwezifo. Kodwa ububi ukuthi kudingeka kunakekelwe ukuhlela umjikelezo wokuzalela ukuze kugwenywe ukuphazamiseka kanye nethonya elihambisanayo phakathi kwemikhiqizo yasemanzini kanye nezitshalo.

Izinzuzo kanye Nezinselele Zobuchwepheshe Bokulima I-Roche Shrimp:

1. Izinzuzo zobuchwepheshe bokulima izimfanzi zeRoche zifaka phakathi okulandelayo:
I-Roche shrimp iwumkhiqizo wasemanzini onenani eliphezulu lokudla okunomsoco kanye nesidingo esikhulu semakethe, okungaletha izinzuzo eziphezulu kwezomnotho.
2. I-Roche shrimp iyisilwane esidla yonke inyama esinokudla okuhlukahlukene, esingasebenzisa ukudla kwemvelo kanye nokudla okunenani eliphansi emanzini ukuze sinciphise izindleko zokuzalanisa.
3. I-Roche shrimp iyisilwane esivumelana nezimo kakhulu esinobubanzi obukhulu bamazinga okushisa nokuphila kanye nosawoti, futhi singakhuliswa ezindaweni ezahlukene zamanzi, okwandisa ukuguquguquka kokufuywa kwezinhlanzi.
4. I-Roche shrimp iyisilwane esikhula ngokushesha esinomjikelezo wokukhula omfushane kanye nesivuno esikhulu, okunganciphisa umjikelezo wokuzalanisa futhi kuthuthukise ukusebenza kahle kokuzalanisa.
5. I-Roche shrimp iyisilwane esifanelekile ukulima okuxubile kanye nokulima ngokushintshana kwezitshalo, okungahambisana nezinye izilwane zasemanzini kanye nezitshalo, kuthuthukise umkhiqizo wamanzi, futhi kufezwe intuthuko ehlukahlukene yokufuya izilwane zasemanzini kanye nezolimo.
Izinselele zobuchwepheshe bokulima izimfanzi zeRoche zifaka phakathi okulandelayo:
1. I-Roche shrimp iyisilwane esidinga ikhwalithi ephezulu yamanzi, futhi ukukhula kwayo kuthinteka kakhulu yikhwalithi yamanzi. Kuyadingeka ukuqinisa ukuqapha nokuphatha ikhwalithi yamanzi ukuze kuvinjelwe ukungcoliswa kwamanzi kanye nokuwohloka kwawo.
2. I-Roche shrimp iyisilwane esivame ukungenwa yizifo, esinomzimba ophansi futhi esisengozini yokuthola izifo ezinjengama-bacteria, amagciwane, isikhunta kanye nezinambuzane. Ngakho-ke, kubalulekile ukuqinisa ukuvimbela nokulawula izifo ukuze kuncishiswe ukufa nokulahlekelwa yi-Roche shrimp.
3. I-Roche shrimp iyisilwane esivame ukuba yizidlani, esinomehluko omkhulu ngesilinganiso sobulili kanye nosayizi womzimba, okungaholela ekuncintisaneni nasekuhlaselweni phakathi kwe-shrimp yesilisa. Ngakho-ke, kubalulekile ukuqinisa ukulawulwa kwesilinganiso sobulili kanye nokufana kobukhulu bomzimba ukuze kuncishiswe izingxabano kanye nokulimala phakathi kwe-Roche shrimp.
4. I-Roche shrimp iyisilwane esithintekayo ukuguquguquka kwemakethe, futhi intengo kanye nesidingo sayo kuyahlukahluka ngokwezinkathi nezifunda. Kuyadingeka ukuqinisa uphenyo lwemakethe kanye nokuhlaziywa, ukwakha isikali sokuzalanisa esifanele kanye nemigomo, nokugwema ukungalingani kokuhlinzekwa kwezidingo kanye nokwehla kwentengo.

I-DMPT (Dimethyl - β - Propionate Thiophene) inezinzuzo ezilandelayo ezibalulekile ekulimeni kwezinhlanzi, ikakhulukazi ekulimeni izimfanzi:

1. Thuthukisa ukusebenza kahle kokudla
I-DMPT ikhulisa kakhulu imvamisa yokudla kanye nesivinini, ifinyeza isikhathi sokudla, futhi inciphisa imfucuza yokudla ngokuvuselela ama-receptor e-shrimp anukayo futhi adla ukudla. Ucwaningo lukhombisile ukuthi ukwengeza i-DMPT ekudleni kungandisa izinga lokusetshenziswa cishe ngo-25% -30% futhi kunciphise ingozi yokungcoliswa kwamanzi.
Khuthaza ukukhula nokubola.
2. I-DMPT ingasheshisa umjikelezo wokubola kwezinhlanzi futhi ifinyeze umjikelezo wokukhula. Okwamanje, isakhiwo sayo esiqukethe isibabule singakhuthaza ukugaywa kwama-amino acid, sithuthukise ukusetshenziswa kwama-amino acid, futhi sithuthukise ukusebenza kahle kokukhula.
3. Thuthukisa ikhwalithi yenyama kanye nenani elingabizi.

4. I-DMPT ingathuthukisa ukunambitheka kwenyama kwe-shrimp, inikeze i-shrimp yamanzi ahlanzekile ukunambitheka okusha nokumnandi okufana nokwe-shrimp yasolwandle, okuthuthukisa ukuncintisana emakethe.

5. Ukuphepha Nokuvikelwa Kwemvelo.

6. I-DMPT shrimp ayinabo ubuthi, inezinsalela ezincane, futhi ihlangabezana nezidingo ze-green aquaculture.
